Setting Up the Time Based One Time Passcode Authentication Method

Last modified 11/14/2024

Time-based one-time passcode (TOTP) is a standard protocol. Azure MFA, which is used to operate Illinois State University's MFA, allows authenticators that support the TOTP protocol to be used. Primary examples include the Google Authenticator, Duo Mobile, and password managers like LastPass and Bitwarden. 

Note:

This method provides an additional option for end users where they do not have, or want to use, a personal phone/smartphone and do not want a hardware token either.

  1. Navigate to account.illinoisstate.edu.
  2. Log in with your ULID and password.
  3. Upon logging in, click the Change MFA Devices button next to Multi-Factor Authentication. (See Figure 1).

  4. Press the Manage Devices button located at the bottom. (See Figure 2).

  5. You may be prompted to log in using your ISU email account, or even authenticate your login with your preferred MFA method (Authenticator app, phone call, text, etc.).
  6. Once you are in the Security Info tab, you should see the Default Sign in Method section with the Authenticator app - notification method as your main method. To change it to One-Time Password, click Change and you will then modify your method to Authenticator App or Hardware Token - Code in the drop down menu that appears (See Figures 3 and 4).
